MANUFACTURE OFFOOTWEAR Filed June 20, 1945 i 3 Sheets-Sheet 3v PatentedOct. 14, 1947 UNITED STATES PATENT OFFICE 15 Claims.

This invention relates to an improvement in the manufacture of footwearand more specilically to a development of the lasting method and machinedisclosed in the United States patents to Kamborian, Nos. 2,235,887, and2,235,888, granted March 25, 1941.

Both the above patents relate to the lasting of the toe of a shoe uppersupported upon a last in the normal (bottom-down) position and includethe steps of so supporting the last that, after the lasting margin ofthe upper at the toe has been seized by gripping means, the last isrocked to raise the toe so that the upper is drawn down snugly over thevlast, and subsequently wiping the lasting margin inwardly below andagainst the bottom surface of a sole also carried by the last, suchwiping operation being performed by instrumentalities independent of thegripping instrumentalities.

According to the present invention the shoe being lasted is heldstationary in the normal (bottom-down) position and the lasting marginof the upper is seized by movable grippers which, seriatim, draw theupper snugly over the last and wipe the lasting margin inwardly belowand against the bottom surface of the sole. The lasting margin, whileheld by the grippers against the sole, is secured to the sole.Mechanical fastening means are herein shown and described for thatpurpose, but it will be understood that the margin may, if desired, bebonded to the sole by a suitable cement or adhesive. The grippers andthe fastening means at each side of the last are mounted upon movablesupporting structures or units and suitable means is provided to actuatethe units and to cause the grippers to move, and to cause the fasteningmeans to function while the grippers hold the margin against the sole.

The primary object of this invention resides in the method of and meansfor lasting the toe of an open toe shoe whereby the toe opening is linedup and the edges of such opening are drawn down to the wood of the lastal1 Within the vision of the operator who is able to make anyadjustments necessary as the lasting takes place, as for example toposition the toe opening for the right and left of a pair of shoes.

Another object of this invention is to provide means by which the upperon a stationary last in the normal (bottom-down) position is pulled overand lasted at the forepart of the shoe, such means comprising movablegrippers which, having seized the lasting margin of the upper, pull theupper down snugly over the last and Wipe the lasting margins under asole carried by the last and hold them against the bottom surfacethereof, thus distinguishing from the practice heretofore followedwherein two independent in- 2 strumentalities are employed as in thepatents mentioned above.

Another object of this invention is to provide a movable unit at eachside of the last which unit includes means for gripping the lastingmargin `of the upper and means for securing such lasting margin to theinsole of the shoe by mechanical fastening means, e. g., staples, andsuitable means by which the unit is moved to cause the gripping means,after seizing the lasting margin, to draw the upper snugly about thelast and to Wipe the lasting margin under the insole and by which thefastening means is actuated after the lasting margin has been wiped.

A further object of the invention resides in the pivotal mounting of apair of the units above mentioned for the toe of the shoe and theprovision of means whereby, as the units are advanced to wipe thelasting margin under the sole, they are swung through an arc ofapproximately twenty ve degrees, thereby drawing the upper down snuglyover the toe of the last.

Other objects of the invention will appear from a consideration of thefollowing description and of the drawings which form a part thereof andin which: l

Fig. 10 is a bottom plan view of a shoe showing the upper lasted at thetoe and shank.

This invention is particularly applicable to the lasting of open toeshoes and has been illustrated in the drawings and will be described asso employed. Heretofore, after assembling the upper and ins-ole upon alast, the upper is first spindied, pulled over and side lasted and thenthe lasting of th upper at the toe, which had been tacked after pullingover, is performed. According to the present invention the upper at thetoe is pulled over and lasted in a single operation without the use oftacks. Moreover when this operation takes place, the shoe is in thenormal (bottom-down) Vplatform or table I which is suitably supported byany desired means or which may be the top sur-` face of a bench. A shaft2, extending longitudinally of the table, is supported in bearings 3secured to the under face of the table and is driven by a suitablesource of power (not shown), e. g., av

motor or other source of power driving through a single revolutionclutch.

The table I is out away at the center to provide a recess l above whichthe forepart of a last 5 (carrying van upper 6 and an insole 15) isarranged in preparation for the lasting operation. The heel kof the last5 rests in a support l (Fig. 3) adjustably mounted in a slot 8 in thetable I and arranged to be raised, or shifted longitudinally as requiredso that lasts of various sizes can be accommodated in the machine. Ifdesired there may also be provided a toe rest 9 (Fig. 1) of any desiredconstruction.

' 'I'.wo slides le are mounted in transversey guides II in the table Ifor reciprocation toward and from the recess ll by the action of groovesI2 in cams I3 fixed to the shaft 2, tongues I4 projecting downwardlyfrom the slides I carrying rollers I5 which engage the cam grooves I2.Supported by the slides I and within the recess 4 is a pair of lastingunits I6 each comprising means for grip-` ping andl stapling the lastingmargins of the upper at the forepart of the shoe. Each unit is pivotallyconnected atY I'I to a slide I0 and is reciprocable therewith. Pivotallyconnected Yto the outer face of each unit I6 is one end of an arm I8,theV other end of the arm terminating in an upwardly projecting pin I 9,which enters an inclined slot 2E! in the table I below the slide IB.Pivoted to the inner faces of the units I are gripper jaws 2i. The jaws2l are normally open as shown in Fig. 2 and are closed by any suitablemeans as, for example, an arm 22 (integral with the jaw and extendingsubstantially at right Aangles thereto through a notch 23 formed in theunit I6) and a link 24 lwhich connects the free end of the arm 22 with atreadle (not shown).

The mechanical fastener applying means incorporated in each unit I6 ofthe illustrated machineis vadapted to form and drive staples through'slots 25 in the upper face of the unit. The staple kforming and drivingmechanism 26 (Figs. 6 and 7) is mounted in a chamber 2'I formed in theunit I and comprises a pair of anvils 28, a vertically movable slide,and a pail' 0f drivers 29, each of which terminates at its upper end ina tongue 3U positioned and dimensioned to enter a slot 25 when thedrivers 2S are raised. The vertically movable slide comprises a centralblock 3l (Fig. 6) and side blocks 32 connected in parallel by aY plate33 (Fig. '7) and spaced apart to provide recesses 34 in which thedrivers 29 travel. The sides of the blocks 32 are milled to providegrooveswhich receive tongues projecting from the sideedges ofthe drivers2S, and the ends of the blocks 32-are similarly milled to receive thewire from which the staples are formed.

A U-shaped plunger 35, integral with the drivers 29 or secured in anysuitablemanner for movement therewith, projects from the bottom wall ofthe .chamber 2l. Supported in a sleeve 36 mounted on the central block3| of the slide is a cross rod 3l on each end of which is pivoted a tripe 38. Each trip 38 is normally inclined so that its lower end enters anotch 39 in a driver 29 and is yieldably held therein by a spring dobetween the surface of the driver and the upper end of the trip. Fixedto the side walls of the chamber 2'I is a cross bar el (Fig. 7). theupper end of each trip 3s is beveled so that, as the drivers 29 advance,the trips will engage the bar il and be actuated thereby.

PivotedV upon the outer face of the unit I6 are bell crank levers d2 thearms of which pass through slots 43 in the unit inV alignment withthe'side .blocks 32. Each arm of each lever terminates in a roller, theroller on one arm entering and remaining in a'poclret le formed on theunder side of an anvil 23, and the roller on the other arm being in thepath of travel of Ya pair of spaced ears 45 and i6 fixed to thecorrespond- Y ing side block 32. Springs el', each connected at one endto the cross bar il and at the other end to the central block 3! of theslide and to the drivers 25,.respectively, hold the slide and drivers 29normally vinthe position'shown in Fig. 6. Projecting into the chamber 2lfromrthe top wall thereof are blades i8 and t9. The blade d8, midwaybetween the slots 25, is positioned for shearing contact with one wallof a notch 5i) formed in the central block 3! of the slide. The blade $9at one side of the chamber 2l is positioned for shearing contact withthe outer face of the adjacentblock 32. Y

The staples are cut and formed from wire fed into the chamber 2l throughan orifice 5l (Fig. 6). The wire is supplied from a reel 52, supportedin the unit I6, through a bent tube 53 and is. advanced by a nipper 54so' constructed that it will seize and feedvthe wire when travelingtoward the chamber 2'! and will release the wire when traveling in theopposite direction. Feed nippers of this type are old and well known andhence more detailed description is believed to be unnecessary. Thenipper 5d is reciprocated by means of an arm 55 fixed on the shaft 55which supports the reel 52, and bifurcated at its free end to engage the'nipper 54. Another arm 5l, xed to the shaft 55, is similarly bifurcatedto engage an arm 58 integral with or :fixed to the gripper jaw 2l andpassing through a slot 59 in the unit I6.

The actuation of the staple forming and driving mechanism is controlledVby a cam 5B ixed upon the shaft 2 midway between the units I 3, and arollery 5I carried by an arm EZand in contact with the periphery of thecam (Fig. 4). The arm 62 is pivoted at one end upon an angular bracket63 Xed to the under face of the table l. The other end of the arm e2 isbifurcated to engage a sleeve 64 on a post 5 which supports a crossplate 66. The plate 65 extends below the plungers 35 (see Fig. 2) andthe post S5 is guidedfor reciprocation in a bushing I'i formed at thefree end of the bracket 63. A spring 68, surrounding the post 55,yieldably holds the roller 6! on the arm 62 in contact with the cam Si)and, when the roller 6I enters a depression 69 in the periphery of thecam, causes the arm e2 to raise the plate 66 and actuate the plungers35. Mountedin each plunger 35 is a depressible plate V'lil (Fig. 6)resting upon a. spring 'il and adapted, when the plunger is raised, toContact the lower end of the middle block 3l of the slide for a purposewhich` will be pointed out hereinbelow.

The operation of the toe lasting machine shown in Fig. 1, in the lastingof the upper 6 of an opentoe shoe, will now be described. The operatorThe outer surface of` places the last 5, with the insole 15 xed to thebottom surface (as by the tacks 1G) and with the upper 6 slippedthereover, in position, bottom-y down upon the heel and toe rests l and9. The lasting margins of the upper are inserted between the jaws 2! andthe inner surfaces of the units I6. Since the toe of the shoe is clearlyvisible to the operator, any necessary shifting either of the last or ofthe upper-which, contrary to the usual practice, yhas not beenpreviously side lastedcan be made so as to insure that the notch in thetoe of the upper is in the correct position for the shoe being lasted. twill be noted that the table l is preferably inclined (see Figs. 3 and4) so that the operato-r can determine visually that the upper isuniformly positioned on the last. The jaws 2l are then caused to gripthe lasting margins, as by depressing the treadle (not shown). Thismovement of the jaws Zlalso, through the arms 5l, causes the nipper 54to advance wire from the reel 53 through the orifice 5I. The wire entersthe grooves in the upper ends oi the blocks 3l, 32 and rests thereinbelow the anvils 23 and blades 48 and t9.

The shaft 2 is then set in rotation and the lasting operation iscompleted during a lsingle rotation of the shaft 2. The slides it?approach each other carrying the units iii which, due to the engagementof the pins i@ on the arms Iii with the slots 253, are swung from theparallel position shown in Fig. l into the inclined position shown inFig. 5, whereby the upper is pulled over the last and the grippedlasting margins of the upper are wiped under the bottom of the insole'l5 in position to be secured thereto by meH chanical fastening means.It will be noted that this inward movement of the units is along arcu"ate paths resulting from the combination of a bodily linear travel andan arcuate travel at the termination of which the units are below theinsole in positions approximately parallel'to the contour of the edge of the forepart (see Fig. 5). The cam 6i! is so mounted upon the shaft 2that as soon as the units reach the position shown in Fig. 5, the arm 62is released and the plungers 35 are raised to form and drive thestaples. Since the trips 38 are in the notches 3Q the drivers 29 and theslide are raised simultaneously. The blocks 3l and 32 of the slide actto sever the wire5 fed by the nipper 54, at the blades i8 and "i9 and tobend the severed portionsvinto staples about the anvils 28. When thestaples have been so formed, the trips 38 engage the cross bar 4l anddisengage the slide from the drivers which continue to advance and atthe same time the levers d2 are struck by the ears 4S to retract theanvils 2B, leaving the formed staples in the grooves milled in the sidesof the blocks 3l, and the staples are forced by the drivers 2Q throughthe slots 25 into the lasting margins to secure them to the sole l5.

The cam titi then returns the arms 62 into the position shown in Fig.whereupon the springs 4l return the slide and drivers 29 to the positionshown in Fig. 6. The plate l@ and spring 'il permit the plungers 35 tocontinue to advance the drivers 29 after the slide has reached the limitof its travel. As the slide returns to its normal position, the ears i5engage the bell crank levers i2 and advance the anvils 28 to theirnormal position. Concomitantly with this action of cam iii), the cams i3retract the slides IG. drawing the units l s back into parallelism.Since the anvils 28 Droiect from the outer face of the units intocontact with the ends of the slides,

6 they will be advanced thereby in case the levers 42 fail to completesuch advance. The last with the toe of the upper xed to the sole is thenready for further treatment as, for example, the lasting at the shank bythe machine shown in Figs. Band 9.

The machine for lasting the upper at the shank of the shoe correspondsgenerally in structure and operation to the machine described above andthe same reference numerals are employed. Since the lasting units i5remain parallel at all times they are rigidly secured to the ends of theslides lil in any desired manner. The contour .of the gripper jaws 2lis, however, changed as shown in Fig. 9 to correspond with the contourof the shank portion of the last. The staple forming and drivingmechanism is simplied because only a single staple is required at thisportion of the shoe. Consequently only a single slot 25 (Fig, 8) isprovided in each unit and the staple forming and driving mechanism ismodied accordingly.

While certainl embodiments of the invention have been shown anddescribed it will be understood that the invention is not limitedthereto and that other embodiments may be made without departing fromthe spirit and scope of the invention as set forth in the followingclaims.
